What is the Line of Control?

The Line of Control (LoC) is the de facto border between the Indian-administered and Pakistani-administered parts of the former princely state of Jammu & Kashmir. It spans approximately 740 kilometres, running from the Karakoram Pass area near Ladakh in the north to a point near Poonch district in the south. Crucially, the LoC is not a legally recognised international boundary — both India and Pakistan maintain their respective territorial claims over the entire region.

The LoC was established under the Simla Agreement of 2 July 1972, signed by Prime Minister Indira Gandhi and President Zulfikar Ali Bhutto, following the Indo-Pakistan War of 1971. It replaced the earlier Ceasefire Line (CFL) that had been drawn after the 1947-48 First Kashmir War under a UN-mediated ceasefire. The process of demarcation was completed by December 1972, with both sides delineating the line on maps authenticated by military representatives.

The LoC has been one of the most heavily militarised borders in the world, witnessing frequent ceasefire violations, cross-border infiltration by militants, and artillery exchanges. A ceasefire agreement was reinstated in February 2021, which largely held until the spring 2025 India-Pakistan crisis triggered by the Pahalgam terror attack.
